The hair follicles in the butt area can suffer some form of inflammation, making them red and swollen (folliculitis). Often, irritated pores appear like pimples or bumps with a white tip. They can also be painful or itchy. Folliculitis doesn’t just cause pimples on the buttocks, but it can likewise cause breakouts anywhere on the body.
Your choice of clothing can contribute to the development of folliculitis. Tight clothes often cause friction on the skin, thereby irritating the pores and causing inflammation. The material of the clothes can also be a factor. Tight clothes made of nylon or polyester fabric can collect sweat, which, in turn, causes inflammation of the pores and acne.
3. Keratosis Pilaris
Another on our list of possible pimples on buttocks causes is keratosis pilaris.
Unlike the red, inflamed bumps when you have folliculitis, keratosis pilaris causes small, rough bumps on the buttocks. This dermatological condition occurs when there is a buildup of keratin around the pores. Keratin is a protein that creates a protective layer on the surface of the skin. However, when too much keratin accumulates, it causes papules.
There is no specific cause for keratosis pilaris. However, this disease can run in families and often flares up sharply in children, then subsides as the child grows. Although keratosis pilaris can cause annoying butt pimples, it’s usually not dangerous.
4. Boils and Skin Abscess
If the “pimples’’ on your buttocks have a thin layer of skin over fluid, you might have a boil. If the breakouts are swollen and pus-filled, this could be a symptom of a skin abscess. Both conditions can occur anywhere in the body, and they usually result from infections.
While boils are a superficial infection, a skin abscess usually runs deep. Staphylococcus aureus is the most common cause of abscesses, but other bacteria, such as streptococcus or pseudomonas bacteria, can also cause it. Some fungi can also cause abscesses, but skin abscesses caused by fungal infections are rare.
